Vestibulocochlear nerve (VIII) lesion
The VIIIth nerve carries sensory information from the cochlear and vestibular apparatus. The auditory fibres arise from the cochlea and pass to the pontine auditory nucleus. These then project to the temporal lobes. The vestibular nerves arise from the semicircular canals and pass to the vestibular nuclei in the pons, and the cerebellum.
